[embodiment]

See also Fig. 1 to Fig. 5, the utility model electric connector 1 comprises insulating body 11 and is placed in plurality of conductive terminals 12 in the insulating body 11, but wherein insulating body 11 comprises that tabular matrix 111 and frame be located at the hollow framework 112 on the matrix 111.Framework 112 is by some holding unit winding one with matrix 111, and forms an accommodation space therebetween to accommodate chip module 3.

The surface that matrix 111 is accepted chip module 3 is a continuing surface 113, with continuing surface 113 facing surfaces be mating surface 114, this mating surface 114 is connected with group with circuit board 2.

The middle part of matrix 111 is provided with conduction region 115, these conduction region 115 ccontaining conducting terminals 12, and these conducting terminal 12 1 ends electrically conduct with the chip module 3 that is placed in the insulating body 11, and the conducting strip (not shown) of the other end and circuit board 2 electrically conducts.

In the present embodiment, the solid framework 112 of group comprises with the holding unit of matrix 111 and can interfere with each other retaining column 116 and holding hole 121 and reference column 119 location holes 122 that cooperate.
